When Can You See the Sea of Clouds?
The sea of clouds (unkai) is a rare natural phenomenon where clouds spread out below you like an ocean when viewed from higher elevations. While it occurs more easily in mountainous areas and basins such as Yamanashi Prefecture, actually witnessing it requires very specific conditions.

Location：Mountainous regions and basins
